In case there is any confusion, let’s set the record straight: duck hunting with unprotected ears causes hearing loss. As hearing doctors at TETRA, we see what years of waterfowl hunting does to our patients. Recent studies show that people with hearing loss are more likely to develop dementia, Alzheimers and other chronic health problems.* Hearing loss impacts overall health and wellness, and ruins the hunting experience.

So why do 86% percent of hunters NOT use hearing protection? Previous products have distorted the sound of the call, either over-amplified everything or blocked out your surroundings, and simply just weren’t comfortable. We solved those problems with the TETRA Shield Series. Using our patent-pending Specialized Target Optimization™ (STO) voices and calling are clear and natural while AlphaShield Compression reduces loud sounds to safe levels.

Our custom products provide the most personalized fit and protection available.

Our Technology

Specialized Target Optimization
Our hearing devices feature patent pending Specialized Target Optimization™ (STO). STO is the world’s first hearing technology that isolates and enhances the exact frequencies needed to improve hearing for your specific hunting environment. With STO, voices are clear, calling sounds natural, wood duck squeals, whistling wings, and mallard drakes are all easily audible.

TETRA products instantly shut down and instantly recover for sudden loud noises, like gunshots, providing the wearer full protection at the very moment it’s needed. For more sustained loud inputs, like loud calling, AlphaShield Compression™ limits the overall output to a safe level, then returns to normal amplification once the loud input has stopped. Never miss a sound you want to hear, and protect your hearing for life.

ClearComm™  is our proprietary algorithm that accentuates human speech while minimizing noises and distractions that occur outside of the frequency range of human voices. ClearComm is useful for better understanding speech and whispers of hunting partners, hearing speech on the range, as well as in other daily activities that require better hearing.

Research

Hearing and the Brain

Research at Johns Hopkins University suggests that more hearing loss increases the risk of dementia. In one study, people with hearing loss were 24% more likely to have Alzheimer’s.* 

With hearing loss, our brains have to work much harder to make sense of what is being said, and even harder to filter out speech from unwanted background noise. Simply trying to understand conversations requires more mental energy and concentration. 

If basic conversations take up most of our mental energy, there is less opportunity for our brains to sort out and store other information. 

At TETRA, our goal is to minimize hearing loss for hunters and shooters, because research shows if we reduce hearing loss, we can also reduce the chance of getting dementia and Alzheimer’s.

Amazing hearing protection

I have been waterfowl hunting for 20+ years without hearing protection...... big mistake! My ears ring all the time, even when not hunting. I decided to attempt to do something about it and, after much research, decided to purchase the Tetra Waterfowl Customshield. They fit perfect! And they are so easy to take in and out of your ear. I wore them for the first weekend of duck season. They are amazing! The sounds you want/need to hear are amplified.... people talking, ducks making noise, whistling wings, etc. The sounds that hurt were "deadened"..... loud duck calls, shotgun blast, etc. Not completely muffled, just softened. You can still hear a duck call or a shotgun report, just not at ear ringing volume. I was concerned that maybe the wind would be amplified. It is not at all. The lanyard and the carrying case make them easy to wear (and not drop in the water) and to carry in your blind bag. These are the total package!

Your hearing is worth it!

First off, I’ve literally been waiting for years for someone to develop what Tetra has designed. I’ve tried the alphas and loved the tech but my ear canals are very small and so had to go customs. These are more expensive than my Benelli BUT HEAR ME ON THIS all my buddies are going deaf and I’ve always used hearing protection. These are 100 times better than Howard Leights sportmuffs for a couple reasons. 1) the directional hearing is phenomenal 2) the calling volume dampening is phenomenal, 3) the cut out of the shotgun blast and reopening of the hearing is instantaneous to the point that I wondered if they even closed except my ears weren’t ringing. 4) very very comfortable. Most guys I know take care of everything except themselves. Let me do you a solid and say, treat yourself to something you need. You won’t regret it. PS Bill and David will go the extra extra mile to treat you right.

TETRA Hearing Devices for Hunting

Thank you so for the great review! We are honored to have customers like you. There are so many awesome hunting traditions worthy of being passed down to our kids. Creating hearing loss because we love to shoot ducks can not be one of them! Have a great and safe season.

Natural sound

I’m a lifelong duck hunter and have always tried to protect my hearing. These custom products are the best hearing protection I’ve ever worn. Blowing a call sounds natural but softer. Gunshots sound normal, but softer. If you are looking for a way to save your hearing and still enjoy your hunt, this is it.

Great in the dove field

My Dad got me some CustomShields and I wore them for the first time yesterday on a Dove hunt. They were really comfortable, voices were clear, and I could easily tell where sounds were coming from in the field. These are great!
